Well update,
This thing is a blast is all I can say. I played around with it earlier in the day in the driveway just putting around and noticed it would become quiet and normal sounding once it got going just as its rolling to a stop does it make that noise, so ran it a bit slowly then checked the gears every so often and they were fine, this was just on a 2s. Then got the adapter wired up and a second lipo charged so I had 2 of my 2s lipos in there running like a 4s and hauled it off to the ditch area. Most of the guys are running 6s which to me is to much unless you just wanna street runs in a offroad enviroment I think it will eat up the drivetrain, the 4s is perfect I think and it never got hot so im pretty sure I can go up a couple teeth, even so its fast now.
